Judges 11:21 Meaning and Commentary

Judges 11:21

And the Lord God of Israel delivered Sihon and all his people
into the hand of Israel
So that as Sihon, his people, and his country, fell into the hands of Israel through the victory the Lord gave them over him, they had a divine right to the land now in dispute:

and they smote them:
destroyed him and all his people, as they were ordered to destroy the seven nations of Canaan, of which the Amorites were one, ( Deuteronomy 7:1 ) ,

so Israel possessed all the land of the Amorites, the inhabitants of
that country;
by means of the above victory they came into the lawful and rightful possession of all the land that belonged to the Amorites, who were at that time, and none else, the inhabitants of it; and therefore the Ammonites could have no claim to it, nor was any made till now.

Judges 11:21 In-Context

19 And Israel sent men to Sihon, king of the Amorites, the king of Heshbon; and Israel said to him, Let me now go through your land to my place.

20 But Sihon would not give way and let Israel go through his land; and Sihon got together all his people, and put his army in position in Jahaz, and made war on Israel.

21 And the Lord, the God of Israel, gave Sihon and all his people into the hands of Israel, and they overcame them; so all the land of the Amorites, the people of that land, became Israel's.

22 All the limit of the Amorites was theirs, from the Arnon as far as the Jabbok and from the waste land even to Jordan.

23 So now the Lord, the God of Israel, has taken away their land from the Amorites and given it to his people Israel; are you then to have it?
